Problems look mighty small from 150 miles up.

BIG HEADLINE posted:

the Navy's already considered suicide drones, considering their adding Bushmaster cannon to a fair number of ships.


After this clip from the attack I finally get why the US Navy is so concerned about swarm attacks, both the deck guns and helicopter struggle to take out one or two drones and it looks like it got well within the range that it could have let off a missile or torpedo if it had one.

This plus the already existing threats from drones and missiles leads me to believe a fleet will need to include ships that are dedicated solely to point defense in the near future. A small ship with something like 8 Phalanx CIWS and way more ammo for them than usual. I imagine Russia struggled to intercept these for reasons related to why Moskva sank, but the success here will encourage more competent nations to invest in this form of attack.

EDIT: it occurs to me another reason why these naval loitering-munitions are better than either torpedoes or anti-ship missiles. They're freeboard and draft are both so small that they're riding basically inside the waves, so radar has a hard time seeing it between troughs, and while sonar picks it up most weapons designed to work in tandem with sonar aren't designed for targets so fast, small and shallow. It's a fantastic exploit of most modern defenses.

I figured the U.S. Navy's concerns about swarm attacks came from their experiences with the Cole and navigating in super-shallow and crowded Gulf.

"All it takes is one." You might not be able to sink a U.S. warship outright, but rendering one combat-ineffective seems to be a more attainable goal (between exhausted crews, swarm attacks of whatever flavor you want, and highly visible and slow moving cargo ships).

The USN is still having convulsions over the Beirut barracks bombings in 1983, when every civilian light plane or speedboat was imagined to be a potential kamikaze from then on. That's when the Stinger teams started showing up on Med-deployed ships, and the process that ended up with the 25mm mounts started then, too. They'd just started to ease back on that when the Cole bombing happened.

Probably just run a drone into a cargo ship bridge should shut down everything. Navy doesn't have the forces for escorts.

Theres a lot of development with ASVs right now for swarm defense.

Well don't you know I'm caught in a trap?

Madurai posted:

The reactor vessel itself? Sure. The fractal spaghetti of plumbing coming out of it? A different story. Underwater shock is scary poo poo.

That is almost all designed to be isolated rapidly in an emergency, and even in port there will be an operator stationed 24/7 to do so, and that which isn't, well, a coolant leak =/= to a sudden catastrophic breach of the vessel.

The Russian submarine Kursk had a torpedo explode INSIDE her hull, and several watertight compartments survived, as did several extremely unfortunate sailors. Her reactor vessel remained intact with no radiation release, as far as I'm aware.

Picture for reference.



(This isn't very typical, I'd like to make that point)

IPCRESS posted:

Happy to be corrected, but I don't think they need to breach the pressure hull to sink the submarine: Stop the ballast tanks from retaining air and I think that ought to do it.

The pressure hull, with all auxiliary tanks internal to it empty, is positively buoyant. You would need to comprise the pressure hull as well. (USS Thresher for example).

After I ran USS Connecticut (a USN fast attack submarine) into an underwater mountain, smashing her sonar sphere through her forward most ballast tanks and puncturing them, we did testing where we flooded (filled) all our main ballast tanks, with our aux tanks (mostly) pumped dry. As expected we remained on the surface. This was to ensure we wouldn't inadvertently sink while we headed home on the surface.

You can trust me on the subject, is what I'm saying.

Fortunately for both Connecticut and San Francisco ballast tanks make great crumple zones, btw.

I would be very interested in reading the results of a nuclear powered boat suffering an explosion directly against the hull, but hopefully I never will.

I saw an analysis some years ago that estimated that hitting a small fast boat with a standard 5” naval gun would need hundreds of rounds on average. Even picking up the incoming boat at the range limit of the gun and at 10 rounds a minute it was going to be iffy to get it before it got into a reasonable range for launching an attack, forget about two.

So, yeah, pretty nervous about swarm attacks.

Hence less expensive shorter range guided munitions such as hellfires have started making their appearance on ships, the navy is spending a lot of effort on guided munitions for their 5” guns and more ships are getting Rolling Airframe Missile launchers which are being upgraded to engage surface targets.
